say i brew a belgian golden strong and i want to add some brett. would it work fine if i drank an orval or two on brew day and tossed the 70 or so degree dregs into the carboy after the sacchromyces and put the carboy in a separate room away from my non-brett beers?

i don't think that the dregs will be enough... I would try to take the dregs and then build them up with starters... I'm no expert on brett beers but I don't think that you would have enough Brett in that to beer to give you the flavor profile you are looking for...
